Grimm/m Patented Mar. 11, 1941 UNITED STATES PATENT OFFICE 6 Claims.

This invention is directed to: an improvement in means for securing a rubber heel to a shoe, and is filed as a continuation in part of my application filed December 4, 1939, Serial No. 307,497.

5 The primary object of the invention is the provision of means whereby the heel may conveniently and simply be secured in place with respect to the shoe through the use of few parts and with minimum mechanical operation.

l The invention is illustrated in the accompanying drawing in which Figure 1 is an inverted perspective View shewing the heel securing means in applied position; Figure `2 is a section on the line 2--2 of Figure 'l showing the securing plate in its initial or arched position;

Figure 3 is a similar View showing the plate in final or flattened position;

Figure 4 is an inverted sectional View showing a modified form of securing means;

Figure 5 is an inverted perspective view of the form shown in Figure 4.

Figure 6 is a section on the line -E of Figure 4.

5 Figure l is a detail View of the arched plate.

As illustrated in the drawing, and more particularly Figures l, 2 and 3, the rubber heel I is of substantially horse-shoe form, with the interior open portion 2 extending through the for- 30 ward portion of the heel. A heel carrying plate 3 is designed to be fixed in any appropriate manner to the sole il of the shoe or the bottom of the heel of a womans shoe. The plate 3 has an outline shape corresponding closely t0 that of the heel, `and is provided with an upstanding edge ange 5, the upper edge of which is inturned to present a pointed relatively narrow spur edge t.

The outer edge of the heel I is formed at an appropriate point with a recess 'I to define a line with which the spur B will engage. The inner margin of the heel is formed with a shoulder 3 at a point about mid-height the inner wall of the heel, the lower edge of the heel below the shoulder 8 being of slightly greater thickness transverse the heel, as at 9, than that por-tion of the heel above the shoulder.

A nut I@ is welded or otherwise secured to the heel plate 3 about centrally of the length and width thereof, or the plate 3 may be formed with a threaded opening in lieu of a nut, as shown in Figure 3. A securing plate Il is of a form to lit within the inner wall of the heel, with its margin seated on the shoulder 8. This securing plate II is normally of slightly arch form, that (Cl. Sli- 36) is, when its` edges are rst placed on the shoulder 8, plate II assumes the position indicated in Figure 2.

The plate II is formed with a central opening I2 and a bolt i3 is provided to pass into this 5 opening and to engage the appropriately located nut lil, carried by :the plate 3, or a threaded opening shown in Figure 3. The outer end of the bolt has a fixed head I4, by which the said bolt may be manipulated to engage the nut.

In this form oi the invention, the plate 3 is secured to the sole 4, and the heel I is slid longitudinally into :the plate 3, being engaged entirely around the heel, except at the forward edge, within the flange 5 and spur 6 of the plate. The securing plate II is then seated on the shoulder 3, and When so applied, the opening I2 in the plate II will be in alignment with the nut I0. The bolt I3 is then passed through the hole I2 and engaged in the nut Il), or threaded opening, as the case may be, and the bolt is tightened through the medium of the fixed head I4 until the normally arched plate I I, as shown in Figure 2, is forced into a flattened position, as shown in Figure 3. This operation of the securing plate I I not only clamps the enlarged portion 9 of the inner wall of the heel onto the plate 3, but spreads the heel proper laterally so as to provide a secure intern-t between the flanges 5 and the spur 6. The heel is thus xedly secured in position in a simple expeditious manner which will permit convenient renewal of the heel when the latter is worn and to be replaced.

In Figures 4 and 5, the heel here indicated at I5 is of more solid form and appropriate out- 35 line.` The heel is formed with a central well I8 of materially less depth than the corresponding dimension of the heel. The juncture of the rear wall lliEL and lthe bottom of the well is bevelled at Ib and correspondingly the junction of the 40 side walls and bottom of the well are bevelled at 16, the front wall of the well being vertical as at Ie. With this form of heel, there is provided a sole carrying plate Il having upstanding edge ange I3 and inturned spur I9 similar to 45 the form first described, the flange and spur cooperating with the heel as in the previous form.

A securing plate 20 is designed to t snugly in the well I5 and is formed with a central opening 2l. The securing plate corresponds substan- 50 tially to the shape of the well and is slightly arched in cross section, as shown in Figure 6. The side and rear edges of the plate are beveled as at Id to correspond with the beveled portions lsb and le@ of the wen wens. A threaded bolt 22 ls passed through the opening 2| and engages a nut 23 carried by and secured to the plate I1, the bolt having a Xed head 24, through which the bolt may be manipulated in engagement with the nut 23. Of course, it is to be understood, a threaded opening in the plate may be used in lieu of the nut.

The tightening of the bolt forces the plate into pressure contact with the rubber heel at the bottom of the well IB, with a tendency to spread that portion of the heel beyond the margin of .the well and so afford an intimate holding contact of the heel and plate I1 in addition .to the securing eifect of the bolt and nut.

By the construction described, the rubber heel can readily and quickly be replaced, at the same time the means employed to fasten the heel to the shoe is such and so located that the recess in the surface of .the heel acts to create a grip when the heel is in use. This particularly true in the form shown in Figures 4 and 5. The recess there shown acts to create a vacuum, hence a grip when the .heel is in use.

What is claimed as new is:

1. A renewable heel structure, including a plate d adapted for permanent attachment to the heel portion of a shoe and having an exterior contour corresponding to a shoe heel, a flange extending substantiallly at right angles from .the side and rear peripheral portions of the plate, a bead projecting inwardly from the free edge of the flange, a removable rubber heel having a contour corresponding to said plate, said rubber heel having an external groove for said bead, and rigid means carried by said plate and engaging said rubber heel in spaced relation to the flange whereby to resist inward flexure of the sides and rear of the peripheral portion of the rubber heel.

2. .The structure of claim 1, wherein ythe rubber heel is recessed on its longitudinal center line, and the rigid means includes a metal plate spanning the recess.

3. The structure of claim 1, wherein the rubber heel is recessed with the recess open at the front and the rubber is of horse-shoe form, and the rigid means includes a metal plate spanning the recess and having screw connection with the first plate.

4. The structure of claim 1, wherein the Wall of the recess is formed with a beveled shoulder and the rigid means is formed with a. beveled edge to cooperate with the beveled shoulder.

5. The structure of claim 1, wherein the Wall of 'the recess is shouldered, and the rigid means includes a metal plate spanning the recess and having beveled edges to engage the beveled edges of the shoulder.

6. A renewable vheel structure, including a plate adapted for permanent attachment to the heel portion of a shoe and having an exterior contour corresponding to a shoe heel, a. flange extending substantially at right angl-es from the side and rear peripheral portions of the plate, a bead projecting inwardly from the free edge of the iiange, a removable rubber heel having Va contour corresponding to said plate, said rubber heel having an external groove for said bead, and a shouldered recess, a metal plate engaging 'the shoulder in the recess, and means cooperating with the met-a1 plate for spreading the rubber heel toward the said means and the flange to lock the plate and heel together.
